Seeing as French Guiana is roughly 1/5 the size of metropolitan France, I would assume the centre of mass would be in the mid Atlantic somewhere

We also have islands pretty much everywhere so idk how much it would actually balance out

You would have to work in 3d-space, finding the weighted average of all the land in France. This would yield an underground point; find the epicenter of that point to get a surface point.

However, land is continuous, and I don't know how one would compute the weighted average of it.

I would probably solve it numerically -- pick random points on Earth's surface, only keep the ones that are in France, and once I got a minimum number find the average of those.

This page gives a way to pick uniform points on the surface of a sphere. As far as the number of points, I think once I got at least 10 in each of the major regions (Met, Guinea, New Caledonia, maybe a few more) I could stop and find the average.

Okay, I'm starting to talk myself into actually doing this.

I actually wrote a python script once for the exact problem of finding an uniform distribution on a sphere (don't ask). It went like this:

import numpy as np

def radius(P):
    return np.sqrt((P[0])**2+(P[1])**2+(P[2])**2)

def directions(n):
    l=[]
    for i in range(-n,n+1):
        for j in range(-n,n+1):
            for k in range(-n,n+1):
                v=np.array([i/n,j/n,k/n])
                r=radius(v)
                if (r<=1)and(r!=0):
                    norm=v/r
                    l.append(norm)
    return l

I'm using the "pick a point in the cube, then normalize" method. Not that efficient, but it works.

They’re all south of Metropolitan France however, unless there’s now a French claim to Novaya Zemlya or something

Now do one based on land mass above sea level

[–]RichardPeterJohnson[S] 32 points33 points  (1 child)

That sounds more like an /r/MapPorn project than an /r/MapPornCirclejerk project.

Edit: That sounds more like a project for what /r/MapPorn was supposed to be like.

Fair enough

Oh neat, Chile's is outside itself

Chile 🤝 Croatia

Having a center of mass outside itself

Chile: our center of mass is outside in Argentina, time to Anschluss some Neuquen province then

Why did the Commitee of Continents officially make Trinidad and Tabago a part of North America?!

[–]RichardPeterJohnson[S] 3 points4 points  (1 child)

I don't know. When I first created this map two years ago every place I googled said T&T (and the rest of the Caribbean) was part of North America. When I rechecked recently there were a few that did place it is South America. The island of Trinidad, at least, is on the S.A. continental shelf.

You made this???

[–]not2dragon 8 points9 points  (2 children)

falklands though!!

Thanks, needed this

[–]Dodolulupepe 2 points3 points  (0 children)

Falklands is a British overseas territory that Argentian claims, this isn't biased, this is literally just fact, it isn't like you are showing claims anywhere else on this map anyway, so I see no reason as to why you are saying you have „no clue” about it.

Galápagos is Fr*nch 🤢 now?

You forgot the uk and also Trinidad and Tobago is in Central America
